Embodiment 1
[0046] Such as figure 1 As shown, this embodiment provides a method for preparing a low-temperature co-fired ceramic green belt, the preparation method comprising:
[0047] Step 1) Mixing CBS-1 glass-ceramic powder and BBZ glass powder to obtain a glass mixture powder, and preparing a glass mixture slurry based on the glass mixture powder.
[0048] As an example, the preparation method of the CBS-1 glass-ceramics powder includes:
[0049] The CBS-1 glass-ceramic powder includes the following components by mass ratio: 35%-37% of CaO, 33%-35% of B 2 o 3 , 27%-30% SiO 2 And 2%-4% TiO 2 ;
[0050] Weigh according to the above ratio, mix and put into a crucible, and melt it into glass liquid at 1450°C-1500°C, quench it into a glass block, and grind it into the CBS-1 glass-ceramic powder by a sand mill;
[0051] Wherein, the particle size D50 of the CBS-1 glass-ceramic powder is 2.0 μm-2.2 μm.
[0052] Specifically, before the mixed raw materials are loaded into the crucible,...
Embodiment 2
[0119] Such as figure 2 As shown, the present embodiment provides a low-temperature co-fired ceramic raw tape, which is formed on the surface of the base film 100, and the raw tape includes from bottom to top: a lower material layer 200, an intermediate material layer 300, and an upper material layer 400; Wherein, the lower material layer 200 is made of glass mixed slurry based on CBS-1 glass-ceramic powder and BBZ glass powder, and the intermediate material layer 300 is made of ceramic powder and CBS-2 glass powder. , ceramic powder and ZBS glass powder or ceramic powder, CBS-2 glass powder and ZBS glass powder made of ceramic glass mixed slurry, the upper material layer 400 is made based on CBS-1 glass-ceramic powder Body and BBZ glass powder made of glass mixed slurry.
[0120] In this example, the base film 100 includes a PET film, of course, other materials that can be used as the base film are also applicable to this example, and the material of the base film is not li...
